Procurement is being rewritten in real time. The Sourcing Manager of 2026 is part strategist, part technologist, part storyteller, part negotiator and entirely comfortable being uncomfortable. They don't process transactions. They orchestrate AI solutions, challenge incumbents, and shape the supplier ecosystem that powers the Un-carrier. This role is for someone who sees AI as leverage, not threat. Who walks into a room of C-Suite executives, simplifies a 40-page deal into one decision, and gets a clean yes or a productive no and moves. I am looking for people that run toward the hard conversations everyone else avoids.

Key functions that you will be part of your day to day:

• Deploy and orchestrate AI agents across the full sourcing lifecycle market intelligence, RFx authoring, response synthesis, redline drafting, should-cost modeling, and supplier scorecards. Treat AI as a co-worker, not a tool: define prompts, evaluation criteria, and human-in-the-loop checkpoints. Measure and continuously improve cycle time, accuracy, and decision quality.
• Own multi-year category strategies for assigned technology spend (SaaS, AI/ML platforms, data, cybersecurity, professional services with focus of Tech Labor). Build supplier ecosystems that out-innovate competitors, not just out-price them. Translate emerging tech (agentic AI, vertical SaaS, foundation model providers) into competitive sourcing plays.
• Lead high-stakes negotiations against incumbent suppliers, internal stakeholders with strong preferences, and entrenched contractual positions. Welcome conflict as the path to better outcomes. Stay calm, curious, and firm when others go quiet or defensive.
• Partner deeply with Technology, Finance, Legal, Cyber, Privacy, and Product to shape demand upstream not just react to it downstream. Be in the room when the technical decision is being made, not after the contract lands on your desk.
• Build defensible should-cost models using AI-assisted research, public filings, benchmark data, and first-principles unit economics. Move negotiations from anchored vendor pricing to fact-based target pricing. Quantify and capture value beyond unit price consumption efficiency, licensing right-sizing, exit costs, and avoided spend.

Job Responsibilities:

• Competitively sourcing technology spend through RFP, RFI and RFQs
• Drafting, negotiating and executing contractual documents including but not limited to master service agreements, statements of work, letter agreements, and purchase orders
• Run market scans and supplier qualification identify net-new entrants, challengers, and emerging players (especially in AI/ML, agentic platforms, vertical SaaS) before they show up in Gartner.
• Building out autonomous agents and tools to help drive productivity, efficiency and overall process improvement
• Partner with technical personnel to interpret technical specifications to commercial and corporate financial requirements
• Summarize and present business cases and agreements for executive review and approval

• 4-7 years Experience managing Business Requirements, Project Plans, Project Schedules and associated project materials in a mid to large size company. (Required)

Knowledge, Skills and Abilities:

• AI Proficiency - Use enterprise AI (ChatGPT Enterprise, Claude, Copilot, internal LLM platforms) as your daily operating system not as a novelty. Draft RFPs, summarize responses, synthesize redlines, model scenarios, prep negotiations. (Required)
• Project Management (Required)
• Category Management (Required)
• Microsoft Office (Required)
• RFP/RFI Development (Required)
